A case of an 85-year-old woman with gradually progressive but severe dyspnea is reported. A thorough workup disclosed platypnea-orthodeoxia syndrome associated with right-to-left shunting through a patent foramen ovale, in the presence of several other recognized risk factors, despite the absence of significant pulmonary hypertension. Successful percutaneous transcatheter closure of the intracardiac defect resulted in resolution of the syndrome.
报告了一例 85 岁女性逐渐加重但严重呼吸困难的病例。彻底的检查显示,尽管没有明显的肺动脉高压,但该患者存在多种其他公认的危险因素,同时合并卵圆孔未闭所致的右向左分流,引起了直立性低氧血症-氧合改善综合征。经皮导管介入卵圆孔未闭封堵术成功,该综合征得以缓解。
